Born into a distinguished line of Tayyibi daʿīs, Idris Imad al-Din became the spiritual leader (Dāʿī al-Muṭlaq) in 1463. He authored the Uyun al-akhbar, an extensive chronicle of Isma'ili history and doctrine. Under his guidance, the community consolidated its teachings and established educational institutions. Idris traveled widely to strengthen ties between Isma'ili communities across Yemen and India. He died in 1468, leaving a rich scholarly legacy that remains central to Tayyibi religious scholarship.

Born in 1775, Ampère made groundbreaking discoveries linking electricity and magnetism. He formulated Ampère's law, which describes the magnetic force between electric currents, and introduced the concept of the solenoid. His lectures and publications laid the foundation for the field of electromagnetism, influencing future scientists like Faraday and Maxwell. Ampère was a professor at the École Polytechnique and the Collège de France, mentoring a generation of researchers. The unit of electric current, the ampere, was named in his honor for his enduring impact on physics and engineering.

Robert Brown conducted pioneering research in plant morphology and taxonomy during the early 19th century. In 1827, he described the erratic movement of pollen grains under a microscope, a discovery later termed Brownian motion. His meticulous study of plant species contributed to the understanding of the cell nucleus and plant classification. Brown served as librarian to the Linnean Society of London and helped standardize botanical nomenclature. His work bridged biology and physics, influencing future developments in statistical mechanics and cell theory.

Edward Everett Hale was a leading Unitarian minister, historian, and writer in 19th-century America. He served as pastor of Boston's South Congregational Church for over fifty years. Hale published hundreds of sermons, essays, and works of fiction and non-fiction across his career. His short story 'The Man Without a Country' remains an enduring classic of patriotic literature. He also advocated for social reforms including prison rehabilitation and public libraries. Hale championed international peace and later served as chaplain to the U.S. Senate. His contributions to American letters and society left a lasting impact.

Adolf von Harnack was a distinguished German theologian and historian of early Christianity. His monumental multi-volume history of dogma traced the development of Christian belief from the apostolic age to the Middle Ages. Harnack championed a liberal Protestant theology focused on the historical Jesus and the gospel's ethical teachings. He served as a professor at the University of Berlin and rector of the Kaiser Wilhelm Society. Harnack influenced both academic theology and church reform movements in Germany. His works on Christian doctrine and church organization remain reference points for scholars.

Frederick Delius was an English composer celebrated for richly atmospheric music evoking nature and emotion. After studying in Germany, he settled in France and developed his unique musical voice combining romantic and impressionistic elements. Delius's notable compositions include 'On Hearing the First Cuckoo in Spring', 'A Village Romeo and Juliet', and 'Florida Suite'. He collaborated with conductor Sir Thomas Beecham, who championed his works in Britain. Despite losing his sight and mobility to illness in later life, Delius continued to compose with the assistance of his wife. His music is admired for its lyrical beauty, harmonic innovation, and evocative orchestration. Delius left a lasting imprint on English music and inspired successive generations of composers.

Born in 1910 in the Netherlands, Willem Jacob van Stockum made significant contributions to mathematical physics and general relativity. His most celebrated work, the van Stockum dust solution, provided one of the few exact models of a rotating universe in Einstein’s field equations. After earning his doctorate at Leiden University, he joined the faculty at the University of Toronto, where he lectured on differential geometry and theoretical physics. During World War II, he applied his analytical skills to aeronautical problems before returning to academic research. Van Stockum’s insights into spacetime structures remain a cornerstone in the study of rotating gravitational systems. He died in a maritime accident in 1944 at the age of 33, leaving a legacy of innovative scholarship.

Xenophon Zolotas was born in 1904 and studied economics at the University of Athens before furthering his education in London. He became a respected economist and academic, holding professorships and advising the Bank of Greece. In 1989, he was appointed interim Prime Minister during a political impasse, leading a non-partisan caretaker government focused on fiscal stability. Zolotas was known for his pragmatic approach to monetary policy and his influential publications on economic planning. His leadership helped guide Greece through a delicate transition period. He lived to be 100, passing away in 2004 and leaving a legacy as both a statesman and scholar.

Augie Auer was born in 1940 in the United States and earned a doctorate in meteorology. He worked with the U.S. Weather Bureau before moving to New Zealand in the late 1970s to join the national meteorological service. Auer served as director of forecasting, becoming a prominent public figure through regular media appearances. He was known for his ability to explain complex weather phenomena in accessible terms. Auer also contributed to research on Southern Hemisphere climate patterns and advocated for climate change awareness. He died in 2007, remembered for his impact on meteorological practice in New Zealand.

Georges Mathieu emerged in the 1940s as a leading figure in post-war European abstraction, founding the tachisme movement that emphasized spontaneous, calligraphic strokes. Born in 1921, he broke from tradition by creating large-scale paintings in public performances, highlighting the act of creation itself. His work gained international acclaim and influenced the development of abstract expressionism in Europe. Mathieu also served as a professor at the École des Beaux-Arts in Lille, nurturing a generation of artists through his teachings. He wrote extensively on art theory, contributing to critical discourse on modern painting. Mathieu passed away in 2012, and his bold canvases continue to captivate audiences around the world.

Born in 1917, Robert M. Grant earned his doctorate in theology and began teaching New Testament studies in the 1940s. He joined Yale Divinity School faculty, where he served for over four decades, shaping generations of biblical scholars. Grant authored landmark works such as 'A Historical Introduction to the New Testament' (1963), cementing his academic reputation. He held leadership roles in professional societies, including the Society of Biblical Literature. Throughout his career, he contributed to ecumenical dialogues and interdisciplinary research in theology. He passed away on 10 June 2014, leaving a profound legacy in the field of biblical scholarship.

Theodore John Kaczynski, born in 1942, was a mathematical prodigy who earned his PhD from the University of Michigan. He briefly taught at the University of California, Berkeley before retreating to a secluded cabin in Montana. Between 1978 and 1995, he conducted a bombing campaign against universities and airlines, killing three people and injuring 23. Kaczynski's 35,000-word manifesto 'Industrial Society and Its Future' was published in 1995 after his demands. He was arrested in 1996 and later sentenced to life in prison without parole after pleading guilty. Kaczynski died in 2023, leaving a complex legacy as both an intellectual and a criminal.
